ECG Construction Spec Book
Since 1991, ECG has provided a Construction Specifications Book (Spec Book) for our participants. The Spec Book provides overhead and underground distribution construction standards for the purpose of standardization and sound construction practices. The ECG Spec Book contains a set of fundamental design standards covering types of overhead and underground distribution construction, with particular focus on attaining proper clearances, spacing, and strength of materials. It is our intent that use of the ECG Spec Book by our participants will ensure adherence to the requirements of the National Electric Safety Code (NESC).
